技术领域Technical field
本申请涉及通信技术领域,尤其涉及一种数据传输方法及设备、芯片系统、计算机可读存储介质。This application relates to the field of communication technology, and in particular to a data transmission method and device, a chip system, and a computer-readable storage medium.
背景技术Background technique
无线局域网(wireless local area network,WLAN)发展至今,新引入了正交频分多址(orthogonal frequency division multiple access,OFDMA)技术,整个带宽被分为多个资源单元(resource unit,RU),也就是说,用户频带资源的分配并不是以信道为单位,而是以资源单元为单位。例如,一个20MHz信道内,可以包含多个RU,形式可以是26-tone RU、52-tone RU、106-tone RU。其中,tone表示子载波个数。此外,RU也可以是242-tone RU、484-tone RU、996-tone RU等形式。Since the development of wireless local area network (WLAN), orthogonal frequency division multiple access (OFDMA) technology has been newly introduced, and the entire bandwidth is divided into multiple resource units (RU). In other words, the allocation of user frequency band resources is not in units of channels, but in units of resources. For example, a 20MHz channel may contain multiple RUs, in the form of 26-tone RU, 52-tone RU, or 106-tone RU. Among them, tone represents the number of sub-carriers. In addition, the RU may also be in the form of 242-tone RU, 484-tone RU, 996-tone RU, etc.
前导码打孔(preamble puncture),或可译为前导码击穿。例如,整个带宽中部分20Mhz信道为空,可称为整个带宽中存在20MHz的孔。对于OFDMA传输,被打孔造成的离散的资源可以分配给不同的站点。对于非OFDMA传输,如OFDM(orthogonal frequency division multiplexing,正交频分复用)传输,若采用前导码打孔,那么剩下的没被打孔的资源也会形成多个RU,合并作为一个整体分配给一个或一组站点(station,STA)。Preamble puncture, or can be translated as preamble puncture. For example, if a part of the 20Mhz channel in the entire bandwidth is empty, it can be said that there are 20MHz holes in the entire bandwidth. For OFDMA transmission, the discrete resources caused by puncturing can be allocated to different sites. For non-OFDMA transmission, such as OFDM (orthogonal frequency division multiplexing) transmission, if preamble puncturing is used, the remaining unpunctured resources will also form multiple RUs, which are combined as a whole Assigned to one or a group of stations (station, STA).
然而,如何指示该多个RU以进行数据传输成为一个亟待解决的问题。However, how to instruct the multiple RUs to perform data transmission has become an urgent problem to be solved.

1、数据分组1. Data grouping
本申请所述的数据传输方法可适应于上行传输,也可适应于下行传输。另外,该数据传输方法还适用于点对点的单用户传输,或下行多用户传输,或上行多用户传输。其中,针对上行多用户传输,该数据传输方法采用的是基于触发帧的上行传输方法。以下分别介绍基于触发帧的数据分组,和非基于触发的数据分组。The data transmission method described in this application can be adapted to uplink transmission and can also be adapted to downlink transmission. In addition, the data transmission method is also suitable for point-to-point single-user transmission, or downlink multi-user transmission, or uplink multi-user transmission. Among them, for uplink multi-user transmission, the data transmission method uses an uplink transmission method based on a trigger frame. The following respectively introduces the data grouping based on the trigger frame and the data grouping that is not based on the trigger.
1.1基于触发帧的数据分组1.1 Data grouping based on trigger frame
数据分组可为高效基于触发帧的物理层协议数据单元(high efficient trigger based physical layer protocol data unit,HE TB PPDU)。基于触发帧发送HE TB PPDU的流程如图2所示,站点接收到触发帧后,可根据该触发帧发送HE TB PPDU。如图2所示,站点接收到触发帧后,可从中解析出与自身的关联标识相匹配的多个用户字段,从而在该多个用户字段中资源单元分配子字段指示的多个资源单元上发送HE TB PPDU。其中,如图2所示,从HE-STF到Data,整个带宽被划分为1个或多个资源单元。The data packet can be a high-efficient trigger-based physical layer protocol data unit (HE TB PPDU). The process of sending HE TB PPDU based on the trigger frame is shown in Figure 2. After the station receives the trigger frame, it can send HE TB PPDU according to the trigger frame. As shown in Figure 2, after the station receives the trigger frame, it can parse out multiple user fields that match its own associated identifier, so that the multiple user fields in the multiple resource units indicated by the resource unit allocation subfield Send HE TB PPDU. Among them, as shown in Figure 2, from HE-STF to Data, the entire bandwidth is divided into one or more resource units.
极高图2所示的HE TB PPDU的结构中各个字段的作用如表1所示。The functions of each field in the HE TB PPDU structure shown in Figure 2 are shown in Table 1.

基于触发帧发送EHT TB PPDU的流程如图3所示,站点接收到触发帧后,可根据该触发帧发送EHT TB PPDU。如图3所示,站点接收到触发帧后,可从中解析出与自身的关联标识相匹配的多个用户字段,从而在该多个用户字段中资源单元分配子字段指示的多个资源单元上发送EHT TB PPDU。其中,如图3所示,从EHT-STF到Data,整个带宽被划分为1个或多个资源单元。图3所示的EHT TB PPDU中各个字段的作用如表2所示。The process of sending EHT TB PPDU based on the trigger frame is shown in Figure 3. After the station receives the trigger frame, it can send EHT TB PPDU according to the trigger frame. As shown in Figure 3, after the station receives the trigger frame, it can parse out multiple user fields that match its own associated identifier, so that the multiple user fields on the multiple resource units indicated by the resource unit allocation subfield Send EHT TB PPDU. Among them, as shown in Figure 3, from EHT-STF to Data, the entire bandwidth is divided into one or more resource units. The functions of each field in the EHT TB PPDU shown in Figure 3 are shown in Table 2.

The trigger frame may also include a frame control (frame control) field, a duration (duration) field, a receive address (RA) field, a transmit address (TA) field, a padding (padding) field, and a frame check sequence (FCS, frame check sequence) field, etc. Among them, the public information field may also be referred to as a public domain or a public information domain or a public field.

1.2 HE MU PPDU1.2 HE MU PPDU
HE TB PPDU的资源单元分配方式与HE MU PPDU的资源单元分配指示方式不同。HE TB PPDU中,如图4所示,资源单元分配是在触发帧中每个用户字段中的资源单元分配子字段中指示的。比如,每个用户字段中都需要8比特的资源单元分配子字段来指示该用户字段被分配的资源单元。而HE MU PPDU的资源单元分配指示方式中,资源单元分配是在高效信令字段中的公共字段中指示的。例如高效多用户物理层协议数据单元(High Efficient  multiple user physical layer protocol data unit,HE MU PPDU)中高效信令字段B(High Efficient Signal Field B,HE-SIG-B)的结构如图5所示,分为两部分。第一部分公共字段(common field)包含1~N个资源单元分配子字段(resource unit Allocation subfield),以及当带宽大于等于80MHz时存在的中间26-子载波资源单元指示(Center-26-tone RU indication)字段,然后是用于校验的循环冗余码(Cyclic Redundancy Code,CRC)以及用于循环解码的尾部(Tail)子字段;第二部分用户特定字段(User Specific field),按照资源单元分配的顺序,存在着1~M个用户字段(User Field),M个用户字段通常是两个为一组,每两个用户字段后跟着一个CRC和Tail字段,但应排除最后一组,在最后一组中,可能会存在1个或者2个用户字段。The resource unit allocation mode of HE TB PPDU is different from the resource unit allocation indication mode of HE MU PPDU. In the HE TB PPDU, as shown in Figure 4, the resource unit allocation is indicated in the resource unit allocation subfield in each user field in the trigger frame. For example, an 8-bit resource unit allocation subfield is required in each user field to indicate the resource unit to which the user field is allocated. In the resource unit allocation indication mode of the HE MU PPDU, the resource unit allocation is indicated in the common field in the high-efficiency signaling field. For example, the structure of High Efficient Multiple User Physical Layer Protocol Data Unit (High Efficient Multiple User Physical Layer Protocol Data Unit, HE MU PPDU) in High Efficient Signal Field B (HE-SIG-B) is shown in Figure 5. , Divided into two parts. The first part of the common field (common field) contains 1 to N resource unit allocation subfields (resource unit Allocation subfield), and the middle 26-subcarrier resource unit indication (Center-26-tone RU indication) that exists when the bandwidth is greater than or equal to 80MHz. ) Field, followed by the Cyclic Redundancy Code (CRC) used for verification and the Tail subfield used for cyclic decoding; the second part of the user specific field (User Specific field) is allocated according to resource units There are 1 to M user fields (User Field), and M user fields are usually two as a group. Every two user fields are followed by a CRC and Tail fields, but the last group should be excluded. In a group, there may be one or two user fields.
极高吞吐量物理层协议数据单元(extremely high throughput physical layer protocol data unit,EHT PPDU)中除了包括上述EHT TB PPDU外,还包括极高吞吐量非基于触发帧的物理层协议数据单元。其中,非基于触发帧的物理层协议数据单元可以与HE MU PPDU类似,也可以分为极高吞吐量单用户物理层协议数据单元(extremely high throughput single user physical layer protocol data unit,EHT SU PPDU)和极高吞吐量多用户物理层协议数据单元(extremely high throughput multiple user physical layer protocol data unit,EHT MU PPDU)。The extremely high throughput physical layer protocol data unit (EHT PPDU) not only includes the above-mentioned EHT TB PPDU, but also includes the extremely high throughput physical layer protocol data unit that is not based on the trigger frame. Among them, the physical layer protocol data unit that is not based on the trigger frame can be similar to HE MU PPDU, or it can be divided into extremely high throughput single user physical layer protocol data unit (extremely high throughput single user physical layer protocol data unit, EHT SU PPDU) And extremely high throughput multi-user physical layer protocol data unit (extremely high throughput multiple user physical layer protocol data unit, EHT MU PPDU).
基于图4和图6可知,EHT TB PPDU的资源单元分配方式与极高吞吐量非基于触发的物理层协议数据单元的资源单元分配指示方式不同。EHT TB PPDU的资源单元分配方式中,如图4所示,资源单元分配是在每个用户字段中的资源单元分配子字段中指示的,比如,每个用户字段中都需要8比特的资源单元分配子字段来指示该用户字段被分配的资源单元。极高吞吐量非基于触发的物理层协议数据单元中,资源单元分配是在极高吞吐量信令字段中的公共字段中指示的,如图6所示。Based on Figures 4 and 6, it can be seen that the resource unit allocation mode of EHT TB PPDU is different from the resource unit allocation indication mode of the very high throughput non-trigger-based physical layer protocol data unit. In the resource unit allocation method of EHT TB PPDU, as shown in Figure 4, the resource unit allocation is indicated in the resource unit allocation subfield in each user field. For example, each user field requires an 8-bit resource unit The allocation subfield indicates the resource unit to which the user field is allocated. In the very high throughput non-trigger-based physical layer protocol data unit, the resource unit allocation is indicated in the common field in the very high throughput signaling field, as shown in FIG. 6.
请参阅图6,图6是本申请实施例提供的一种极高吞吐量非基于触发的物理层协议数据单元的结构示意图。如图6所示,该数据分组包括传统短训练序列(legacy short training field,L-STF)、传统长训练序列(legacy long training field,L-LTF)、传统信令字段(legacy signal field,L-SIG)、重复的传统信令字段(repeated legacy signal field,RL-SIG)、通用信令字段(universal signal field,U-SIG)、极高吞吐率信令字段(extremely high throughput-signal field,EHT-SIG)等。其中,EHT-SIG中分为两部分,第一部分公共字段(common field)包含1~N个资源单元分配子字段(resource unit allocation subfield);第二部分用户特定字段(User Specific field),按照资源单元分配的顺序,存在着1~M个用户字段(User Field)。Please refer to FIG. 6, which is a schematic structural diagram of a non-trigger-based physical layer protocol data unit with extremely high throughput provided by an embodiment of the present application. As shown in Figure 6, the data packet includes the traditional short training sequence (legacy short training field, L-STF), the traditional long training sequence (legacy long training field, L-LTF), and the traditional signaling field (legacy signal field, L-STF). -SIG), repeated legacy signal field (RL-SIG), universal signal field (U-SIG), extremely high throughput-signal field, EHT-SIG) and so on. Among them, EHT-SIG is divided into two parts. The first part of the common field (common field) contains 1 to N resource unit allocation subfields (resource unit allocation subfield); the second part of the user specific field (User Specific field), according to the resource There are 1 to M user fields (User Fields) in the order of unit allocation.
2、OFDMA传输和非OFDMA传输2. OFDMA transmission and non-OFDMA transmission
OFDMA传输是一种多用户通信机制,其适用于802.11ax标准以及之后的AP和STA之间的数据帧交换,整个传输带宽可划分为多个资源单元,分别分配给不同的用户。非OFDMA传输中,整个传输带宽作为一个整体被用于单用户(single user,SU)或者MU-MIMO传输。对于非OFDMA传输,在进行前导码打孔以后,剩下的没被打孔的部分会形成多个RU。非OFDMA传输支持的多RU合并组合情况,等效于非OFDMA传输支持的前导码打孔组合情况。OFDMA transmission is a multi-user communication mechanism, which is suitable for the 802.11ax standard and subsequent data frame exchange between AP and STA. The entire transmission bandwidth can be divided into multiple resource units, which are allocated to different users. In non-OFDMA transmission, the entire transmission bandwidth as a whole is used for single user (single user, SU) or MU-MIMO transmission. For non-OFDMA transmission, after puncturing the preamble, the remaining unpunctured part will form multiple RUs. The combination of multiple RUs supported by non-OFDMA transmission is equivalent to the combination of preamble puncturing supported by non-OFDMA transmission.
3、资源单元3. Resource unit
以20MHz为基本带宽,带宽是20MHz的指数整数倍(如20,40,80,160MHz)。一种可选的实施方式中,将20MHz作为一个信道,802.11的信道分配如图7所示,图7是本申请实施例提供的一种信道分布的示意图,该带宽为160MHz时可划分为主20MHz信道(或简称主信道,Primary 20MHz,P20),从20MHz信道(Secondary 20MHz,S20),从40MHz信道(Secondary 40MHz,S40),从80MHz(Secondary 80MHz,840)信道。一种可选的实施方式,信道1可对应主20MHz信道、信道2对应从20MHz信道、信道3和信道4合并为从40MHz信道、信道5至信道8合并为从80MHz信道。主40MHz信道(或简称主信道,Primary 40MHz,P40)为主20MHz信道所在的40MHz信道;主80MHz信道(或简称主信道,Primary 80MHz,P80)为主20MHz信道所在的80MHz信道。Taking 20MHz as the basic bandwidth, the bandwidth is an exponential integer multiple of 20MHz (such as 20, 40, 80, 160MHz). In an optional implementation manner, 20MHz is used as a channel. The channel allocation of 802.11 is shown in Figure 7. Figure 7 is a schematic diagram of a channel distribution provided by an embodiment of the present application. When the bandwidth is 160MHz, it can be divided into the main 20MHz channel (or primary channel for short, Primary 20MHz, P20), from 20MHz channel (Secondary 20MHz, S20), from 40MHz channel (Secondary 40MHz, S40), from 80MHz (Secondary 80MHz, 840) channel. In an alternative embodiment, channel 1 may correspond to the main 20 MHz channel, channel 2 may correspond to the slave 20 MHz channel, channel 3 and channel 4 are combined into a 40 MHz channel, and channel 5 to channel 8 are combined into a slave 80 MHz channel. The primary 40MHz channel (or Primary 40MHz, P40 for short) is the 40MHz channel where the primary 20MHz channel is located; the primary 80MHz channel (or Primary 80MHz, P80 for short) is the 80MHz channel where the primary 20MHz channel is located.
另一种可选的实施方式中,可将数据分组的带宽划分为多个资源单元(resource unit,RU)。不同大小的资源单元可由不同数量的子载波组合成。例如,不同大小的资源单元可有以下七种:包括996个子载波的资源单元(996-tone RU)、包括484个子载波的资源单元(484-tone RU)、包括484个子载波的资源单元(484-tone RU)、包括106个子载波的资源单元(106-tone RU)、包括26个子载波的资源单元(26-tone RU)、包括52个子载波的资源单元(52-tone RU)、包括2*996个子载波的资源单元(2*996-tone RU)。In another optional implementation manner, the bandwidth of the data packet may be divided into multiple resource units (RU). Resource units of different sizes can be composed of different numbers of subcarriers. For example, resource units of different sizes may have the following seven types: resource unit (996-tone RU) including 996 subcarriers, resource unit (484-tone RU) including 484 subcarriers, resource unit (484-tone RU) including 484 subcarriers -tone RU), resource unit including 106 subcarriers (106-tone RU), resource unit including 26 subcarriers (26-tone RU), resource unit including 52 subcarriers (52-tone RU), including 2* 996 sub-carrier resource units (2*996-tone RU).
请参阅图8,图8是本申请实施例提供的一种80MHz内的资源单元分布示意图。如图8所示,第一行表示80MHz可包括37个26-tone RU,第二行表示80MHz可包括16个52-tone RU,第三行表示80MHz可包括8个106-tone RU,第四行表示80MHz可包括4个242-tone RU,第五行表示80MHz可包括2个484-tone RU,第六行表示80MHz可包括1个996-tone RU。另外,如图8所示,每一行的80MHz内还存在一个由13-tone子单元组成的中间26-tone RU。此外,各行可包括一些保护(guard)子载波,空子载波(图5中阴影部分),或直流(direct current,DC)子载波。Please refer to FIG. 8. FIG. 8 is a schematic diagram of resource unit distribution within 80 MHz provided by an embodiment of the present application. As shown in Figure 8, the first row indicates that 80MHz can include 37 26-tone RUs, the second row indicates that 80MHz can include 16 52-tone RUs, the third row indicates that 80MHz can include 8 106-tone RUs, and the fourth row indicates that 80MHz can include 8 106-tone RUs. The row indicates that 80MHz can include four 242-tone RUs, the fifth row indicates that 80MHz can include two 484-tone RUs, and the sixth row indicates that 80MHz can include one 996-tone RU. In addition, as shown in Figure 8, there is also an intermediate 26-tone RU composed of 13-tone subunits within 80 MHz of each row. In addition, each row may include some guard subcarriers, empty subcarriers (shaded in FIG. 5), or direct current (DC) subcarriers.
如图8所示,20MHz可包括9个26-tone RU,可包括4个52-tone RU,可包括2个106-tone RU,可包括1个242-tone RU。此外,各行可包括一些保护(guard)子载波,空子载波(图5中阴影部分),或直流(direct current,DC)子载波。As shown in Figure 8, 20MHz may include 9 26-tone RUs, may include 4 52-tone RUs, may include 2 106-tone RUs, and may include 1 242-tone RU. In addition, each row may include some guard subcarriers, empty subcarriers (shaded in FIG. 5), or direct current (DC) subcarriers.
如图8所示,40MHz可包括18个26-tone RU,可包括8个52-tone RU,可包括4个106-tone RU,可包括2个242-tone RU,可包括1个484-tone RU。此外,各行可包括一些保护(guard)子载波,空子载波(图5中阴影部分),或直流(direct current,DC)子载波。As shown in Figure 8, 40MHz can include 18 26-tone RUs, 8 52-tone RUs, 4 106-tone RUs, 2 242-tone RUs, and 1 484-tone RU. RU. In addition, each row may include some guard subcarriers, empty subcarriers (shaded in FIG. 5), or direct current (DC) subcarriers.
针对160MHz的带宽或离散的80MHz+80MHz构成的160MHz带宽,可以看作两个图7所示的80MHz的资源单元分布的组合,比如可以包括一个2*996-tone RU,或可以包括26-tone RU,52-tone RU,106-tone RU,242-tone RU,484-tone RU,996-tone RU的各种组合。Regarding the 160MHz bandwidth or the 160MHz bandwidth composed of discrete 80MHz+80MHz, it can be regarded as a combination of two 80MHz resource unit distributions shown in Figure 7, for example, it can include a 2*996-tone RU, or it can include 26-tone. Various combinations of RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU, 996-tone RU.
上述图8所示的各资源单元中,从左到右频率依次升高,最左边的资源单元可以看作最低频率的资源单元,最右边可以看作最高频率的资源单元。如图7所示,80MHz包括的4个242-tone RU,可以从左到右分别进行标号:第一个242-tone RU、第二个242-tone RU、第三个242-tone RU、第四个242-tone RU。其中,第一个242-tone RU、第二个242-tone RU与该80MHz内的频率最低的两个20MHz,按照频率从低到高一一对应;第三个242-tone  RU、第四个242-tone RU与该80MHz内的频率最高的两个20MHz,按照频率从低到高一一对应。由于每80MHz存在一个中间26-tone RU,故上述242-tone RU与其对应的20MHz在频率上并不是完全重合。Among the resource units shown in FIG. 8, the frequencies increase from left to right, the leftmost resource unit can be regarded as the resource unit with the lowest frequency, and the rightmost resource unit can be regarded as the resource unit with the highest frequency. As shown in Figure 7, the 4 242-tone RUs included in 80MHz can be labeled from left to right: the first 242-tone RU, the second 242-tone RU, the third 242-tone RU, and the third 242-tone RU. Four 242-tone RU. Among them, the first 242-tone RU, the second 242-tone RU and the two lowest frequencies within the 80MHz 20MHz correspond one-to-one according to the frequency from low to high; the third 242-tone RU, the fourth The 242-tone RU corresponds to the two highest frequencies of 20MHz within the 80MHz, from low to high in a one-to-one correspondence. Since there is an intermediate 26-tone RU every 80MHz, the above-mentioned 242-tone RU and its corresponding 20MHz do not completely overlap in frequency.
相应地,80MHz包括的2个484-tone RU,可以从左到右分别进行标号:第一个484-tone RU、第二个484-tone RU。该80MHz内的频率最低的40MHz、频率最高的40MHz分别与第一个484-tone RU、第二个484-tone RU,按照频率从低到高一一对应。Correspondingly, the two 484-tone RUs included in 80 MHz can be labeled from left to right: the first 484-tone RU and the second 484-tone RU. The lowest frequency 40MHz and the highest frequency 40MHz within the 80MHz correspond to the first 484-tone RU and the second 484-tone RU respectively, from low to high in a one-to-one correspondence.
由上述内容可知,针对基于触发帧的数据分组,可通过触发帧中每个用户字段中的资源单元分配子字段指示被分配的资源单元,站点可识别出与自身的关联标识相同的用户字段,从这些用户字段中获知被分配的资源单元,以传输基于触发帧的数据分组。针对非基于触发帧的数据分组,可通过信令字段中公共字段中的资源单元分配子字段,获知被分配的资源单元,进而接收数据分组。例如,假设站点被分配的资源单元可以为图7所示的80MHz中的第一个484-tone RU和第四个242-tone RU。It can be seen from the above content that for the data grouping based on the trigger frame, the resource unit allocation subfield in each user field in the trigger frame can be used to indicate the allocated resource unit, and the station can identify the user field that is the same as its own associated identifier. Know the allocated resource units from these user fields to transmit data packets based on the trigger frame. For data packets that are not based on the trigger frame, the resource unit allocation subfield in the common field in the signaling field can be used to learn the allocated resource unit, and then the data packet can be received. For example, it is assumed that the resource units allocated to the site may be the first 484-tone RU and the fourth 242-tone RU in the 80 MHz shown in FIG. 7.
然而,若数据分组的带宽中存在前导码打孔,那么打孔造成的离散的资源,均通过上述所述的资源单元分配子字段指示会因为需指示的资源单元较多而导致信令开销较大。However, if there is preamble puncturing in the bandwidth of the data packet, the discrete resources caused by puncturing are all indicated by the above-mentioned resource unit allocation subfield, which will result in higher signaling overhead due to more resource units to be indicated. Big.
为了降低该开销,本申请实施例通过前导码打孔指示信息,指示数据分组的前导码打孔信息,以进行数据分组的发送或接收。其中,前导码打孔指示信息包括一个或多个指示,一个指示对应一个前导码打孔信息,前导码打孔信息包括前导码打孔的大小和位置,或前导码无打孔等。也就是说,数据分组的带宽中存在部分信道为空,或数据分组的带宽中存在孔,通过指示这些孔的大小和位置,进而站点可在带宽中这些孔之外的资源单元或信道中接收或发送数据分组,以降低信令开销。In order to reduce the overhead, the embodiment of the present application uses the preamble puncturing indication information to indicate the preamble puncturing information of the data packet to send or receive the data packet. The preamble puncturing indication information includes one or more indications, one indication corresponds to one preamble puncturing information, and the preamble puncturing information includes the size and position of the preamble puncturing, or the preamble is not punctured. In other words, some channels in the bandwidth of the data packet are empty, or there are holes in the bandwidth of the data packet. By indicating the size and location of these holes, the station can receive in resource units or channels other than these holes in the bandwidth. Or send data packets to reduce signaling overhead.
例如,假设前导码打孔的大小和位置为图8中第二个242-tone RU,即该第二个242-tone RU对应的80MHz中的第二个20MHz,那么,打孔造成的离散的资源为第一个242-tone RU、第三个242-tone RU、第四个242-tone RU,假设对于非OFDMA传输,该第一个242-tone RU、第三个242-tone RU、第四个242-tone RU均分配给一个站点或一组站点,那么站点对应的资源单元分配子字段就需要指示该第一个242-tone RU、第三个242-tone RU、第四个242-tone RU,或需要分别指示第一个484-tone RU和第四个242-tone RU。而本申请可指示前导码打孔的大小和位置为80MHz中的第二个20MHz,进而,站点基于该前导码打孔信息确定被分配的资源单元,与需要指示至少两个资源单元的方式相比,有利于节省资源单元分配所需的开销。For example, assuming that the size and position of the preamble puncturing are the second 242-tone RU in Figure 8, that is, the second 20MHz of the 80MHz corresponding to the second 242-tone RU, then the discrete puncturing caused The resources are the first 242-tone RU, the third 242-tone RU, and the fourth 242-tone RU. Assuming that for non-OFDMA transmission, the first 242-tone RU, the third 242-tone RU, and the The four 242-tone RUs are all allocated to a site or a group of sites, then the resource unit allocation subfield corresponding to the site needs to indicate the first 242-tone RU, the third 242-tone RU, and the fourth 242-tone RU. Tone RU, or need to indicate the first 484-tone RU and the fourth 242-tone RU respectively. However, this application may indicate that the size and position of the preamble puncturing is the second 20 MHz in 80 MHz. Furthermore, the station determines the allocated resource unit based on the preamble puncturing information, which is the same as the way that at least two resource units need to be indicated. This ratio is conducive to saving the overhead required for resource unit allocation.
以下结合附图和上述相关概念的阐述对本申请或本申请中新增的前导码打孔指示信息的相关内容进行进一步的阐述。The following describes the relevant content of this application or the newly added preamble puncturing indication information in this application in conjunction with the accompanying drawings and the description of the above-mentioned related concepts.

其中,该前导码打孔指示信息包括一个或多个指示,一个指示对应一个前导码打孔信 息。本申请中,前导码打孔指示信息是用于接收端基于其对应的前导码打孔信息,确定被分配的资源单元的,即该前导码打孔指示信息的作用与上文所述的资源单元分配子字段的作用相同。因此,针对基于触发帧的数据分组,该前导码打孔指示信息可包含在触发帧中各用户字段中;针对非基于触发帧的数据分组,该前导码打孔指示信息可包含在数据分组的信令字段中的公共字段中。Wherein, the preamble puncturing indication information includes one or more indications, and one indication corresponds to one preamble puncturing information. In this application, the preamble puncturing indication information is used by the receiving end to determine the allocated resource unit based on its corresponding preamble puncturing information, that is, the preamble puncturing indication information has the same function as the resource mentioned above. The unit allocation subfield has the same effect. Therefore, for a data packet based on a trigger frame, the preamble puncturing indication information can be included in each user field in the trigger frame; for a data packet that is not based on a trigger frame, the preamble puncturing indication information can be included in the data packet. In the common field in the signaling field.
可选的,该前导码打孔指示信息可以为触发帧中用户字段中新增的字段或复用预留字段,或者为数据分组的信令字段中公共字段中新增的字段或复用预留字段。Optionally, the preamble puncturing indication information may be a newly added field or multiplexing reserved field in the user field of the trigger frame, or a newly added field or multiplexing reserved field in the common field of the signaling field of the data packet. Leave the field.
可选的,如图10所示,与图4相比,前导码打孔指示信息可复用触发帧中用户字段中的资源单元分配子字段。例如,如图10所示,假设前导码打孔指示信息包括第一指示和第二指示,两个指示分别指示两个前导码打孔信息。可选的,如图11所示,与图6相比,前导码打孔指示信息可复用EHT-SIG中的资源单元分配子字段。例如,如图11所示,可假设前导码打孔指示信息包括第一指示和第二指示,两个指示分别指示两个前导码打孔信息。Optionally, as shown in FIG. 10, compared with FIG. 4, the preamble puncturing indication information may be multiplexed with the resource unit allocation subfield in the user field in the trigger frame. For example, as shown in FIG. 10, it is assumed that the preamble puncturing indication information includes a first indication and a second indication, and the two indications respectively indicate two preamble puncturing information. Optionally, as shown in FIG. 11, compared with FIG. 6, the preamble puncturing indication information may be multiplexed with the resource unit allocation subfield in the EHT-SIG. For example, as shown in FIG. 11, it may be assumed that the preamble puncturing indication information includes a first indication and a second indication, and the two indications respectively indicate two preamble puncturing information.
102、站点接收前导码打孔指示信息;102. The station receives the preamble puncturing instruction information;
103、站点根据该前导码打孔指示信息,发送或接收数据分组。103. The station sends or receives data packets according to the preamble puncturing instruction information.
其中,若前导码打孔指示信息位于信令字段,如图11所示的EHT-SIG中,站点可将前导码打孔指示信息与数据分组作为一个整体进行接收或发送。Among them, if the preamble puncturing indication information is located in the signaling field, as shown in the EHT-SIG shown in FIG. 11, the station can receive or send the preamble puncturing indication information and the data packet as a whole.
步骤103可以包括:当所述前导码打孔指示信息指示前导码无打孔时,在所述数据分组的带宽上发送或接收所述数据分组;当所述前导码打孔指示信息指示前导码打孔的大小和位置,在所述数据分组的带宽上除所述前导码打孔的大小和位置外的资源单元上,发送或接收所述数据分组。Step 103 may include: when the preamble puncturing indication information indicates that the preamble is not punctured, sending or receiving the data packet on the bandwidth of the data packet; when the preamble puncturing indication information indicates the preamble The size and position of the puncturing are to send or receive the data packet on resource units other than the size and position of the preamble puncturing on the bandwidth of the data packet.
另外,本申请实施例还提供几种可选的前导码打孔信息的指示方式,具体可参见下文所述。In addition, the embodiment of the present application also provides several optional indication methods of the preamble puncturing information. For details, please refer to the following description.
可见,本申请能够基于前导码打孔指示信息间接指示被分配的资源单元,以发送或接收数据分组,与单纯基于资源单元分配子字段直接指示被分配的资源单元的方式相比,本申请有利于降低资源单元分配所需的信令开销。It can be seen that this application can indirectly indicate the allocated resource unit based on the preamble puncturing indication information to send or receive data packets. Compared with the method of directly indicating the allocated resource unit based solely on the resource unit allocation subfield, this application has It is beneficial to reduce the signaling overhead required for resource unit allocation.
请参阅图12,图12为本申请实施例提供的另一种数据传输方法的流程示意图。图12所示的数据传输方法与图9所示的数据传输方法相比,接入点还发送传输方式指示信息。该传输方式指示信息用于指示数据分组的传输方式,例如,站点可基于该传输方式指示信息确定数据分组是OFDMA传输,还是非OFDMA传输。针对非OFDMA传输,前导码打孔导致的离散的多个资源单元,是统一分配给一个用户或一组用户的,即每个用户被分配的资源单元是相同的且通常为多个,因此,与资源单元分配子字段指示多个离散的资源单元的方式相比,本申请采用前导码打孔指示信息,能够降低资源单元指示所需的信令开销。针对OFDMA传输,前导码打孔导致的离散的多个资源单元,是分配给不同用户的,也就是说,对于一个用户,其所需被分配的资源单元为这些离散的资源单元中的部分,故采用资源单元分配子字段来指示,所需的信令开销相对较小。因此,图12所述的数据传输方法,可根据传输方式的不同,采用不同的资源单元指示方法。Please refer to FIG. 12, which is a schematic flowchart of another data transmission method according to an embodiment of the application. Compared with the data transmission method shown in FIG. 9 in the data transmission method shown in FIG. 12, the access point also sends transmission mode indication information. The transmission mode indication information is used to indicate the transmission mode of the data packet. For example, the station may determine whether the data packet is OFDMA transmission or non-OFDMA transmission based on the transmission mode indication information. For non-OFDMA transmission, the discrete multiple resource units caused by preamble puncturing are uniformly allocated to a user or a group of users, that is, the resource units allocated to each user are the same and usually multiple. Therefore, Compared with the manner in which the resource unit allocation subfield indicates multiple discrete resource units, the present application adopts the preamble puncturing indication information, which can reduce the signaling overhead required for resource unit indication. For OFDMA transmission, the discrete multiple resource units caused by preamble puncturing are allocated to different users, that is, for a user, the resource units that need to be allocated are some of these discrete resource units. Therefore, the resource unit allocation subfield is used to indicate, and the required signaling overhead is relatively small. Therefore, the data transmission method described in FIG. 12 can adopt different resource unit indication methods according to different transmission methods.
具体的,如图12所示,该数据传输方法可包括以下步骤:Specifically, as shown in FIG. 12, the data transmission method may include the following steps:
201、接入点发送信令字段或触发帧,所述信令字段或触发帧中包括传输方式指示信息 和前导码打孔指示信息,或传输方式指示信息和资源单元分配子字段;201. An access point sends a signaling field or a trigger frame, where the signaling field or trigger frame includes transmission mode indication information and preamble puncturing indication information, or transmission mode indication information and resource unit allocation subfields;
其中,该信令字段可包括图10所示的U-SIG和EHT-SIG,该触发帧可为图11所示的结构,但并不限于图10所示这些信令字段,以及图11所示的触发帧的结构。其中,这些信令字段如图10所示,是位于PPDU中的,因此,针对非基于触发帧的物理层协议数据单元,接入点可将信令字段与数据分组可一起作为整体发送给接收端,如站点。Wherein, the signaling field may include the U-SIG and EHT-SIG shown in FIG. 10, and the trigger frame may have the structure shown in FIG. 11, but is not limited to the signaling fields shown in FIG. 10 and those shown in FIG. 11. The structure of the trigger frame shown. Among them, these signaling fields are located in the PPDU as shown in Figure 10. Therefore, for the physical layer protocol data unit that is not based on the trigger frame, the access point can send the signaling field and the data packet as a whole to the receiver. End, such as a site.
如图10所示,传输方式指示信息可位于触发帧中的公共字段中,数据分组的带宽也可位于该公共字段中,传输方式指示信息指示非OFDMA传输,资源单元分配子字段的位置为前导码打孔指示信息。另外,针对非OFDMA传输,逐个站点字段的M个用户字段中,各前导码打孔指示信息的内容可以相同。其中,前导码打孔指示信息也可称为前导码打孔指示子字段。As shown in Figure 10, the transmission mode indication information can be located in the common field in the trigger frame, the bandwidth of the data packet can also be located in the common field, the transmission mode indication information indicates non-OFDMA transmission, and the position of the resource unit allocation subfield is the preamble Code punching instructions. In addition, for non-OFDMA transmission, in the M user fields of each site field, the content of the preamble puncturing indication information may be the same. Wherein, the preamble puncturing indication information may also be referred to as the preamble puncturing indication subfield.
如图11所示,传输方式指示信息可位于数据分组的U-SIG中,传输方式指示信息指示非OFDMA传输,EHT-SIG中公共字段中的资源单元分配子字段为前导码打孔指示信息。其中,前导码打孔指示信息也可称为前导码打孔指示子字段。数据分组的带宽也可以可位于U-SIG中。其中,对于非OFDMA传输,M个用户字段分别对应的前导码打孔指示子字段的内容可以相同。用户特定字段中用户字段出现的顺序与对应的前导码打孔指示子字段所指示的前导码打孔信息相一致,站点可以通过读取用户字段中的站点标识(STA ID)来识别自身该用户字段是否属于自己,结合用户字段出现的位置与对应的前导码打孔指示子字段,站点可以知晓自己的前导码打孔信息。As shown in FIG. 11, the transmission mode indication information may be located in the U-SIG of the data packet, the transmission mode indication information indicates non-OFDMA transmission, and the resource unit allocation subfield in the common field in the EHT-SIG is the preamble puncturing indication information. Wherein, the preamble puncturing indication information may also be referred to as the preamble puncturing indication subfield. The bandwidth of the data packet can also be located in the U-SIG. Wherein, for non-OFDMA transmission, the content of the preamble puncturing indication subfields corresponding to the M user fields may be the same. The order in which the user fields appear in the user-specific field is consistent with the preamble puncturing information indicated by the corresponding preamble puncturing indication subfield. The site can identify itself by reading the STA ID in the user field. Whether the field belongs to itself, combining the position where the user field appears and the corresponding preamble puncturing indication subfield, the site can know its own preamble puncturing information.
为了有效地对资源进行复用,在大于等于40MHz的情况下可采用内容信道(content channel,CC)1、CC2的方式来表示EHT-SIG或未来某一代WiFi标准的字段中的内容。例如,当数据分组带宽为40MHz时,存在两个EHT-SIG内容信道,CC1和CC2,如图13所示,在第一个EHT-SIG CC1中可包含前导码打孔指示信息中的第一指示以及所对应的用户字段;第二个EHT-SIG CC2中包含前导码打孔指示信息中的第二指示以及所对应的用户字段,其中,第一指示和第二指示分别对应的用户字段相同。In order to effectively multiplex resources, content channels (CC) 1 and CC2 can be used to represent the content in the fields of EHT-SIG or a future generation of WiFi standards when the frequency is greater than or equal to 40 MHz. For example, when the data packet bandwidth is 40MHz, there are two EHT-SIG content channels, CC1 and CC2. As shown in Figure 13, the first EHT-SIG CC1 can include the first in the preamble puncturing indication information. Indication and the corresponding user field; the second EHT-SIG CC2 contains the second indication in the preamble puncturing indication information and the corresponding user field, where the first indication and the second indication respectively correspond to the same user field .
可选的,在CC1和CC2中可包含相同的前导码打孔指示信息以及所对应的用户字段。通过对CC1与CC2内信息的读取,用户可以完全知晓带宽上的前导码打孔信息,有利于增加该前导码打孔信息传输的可靠性。可选的,前导码打孔指示信息也可以在其中一个CC上出现。Optionally, CC1 and CC2 may contain the same preamble puncturing indication information and the corresponding user field. By reading the information in CC1 and CC2, the user can fully know the preamble puncturing information on the bandwidth, which is beneficial to increase the reliability of the transmission of the preamble puncturing information. Optionally, the preamble puncturing indication information may also appear on one of the CCs.
202、站点接收该信令字段或触发帧;202. The station receives the signaling field or trigger frame.
相应地,这些信令字段如图10所示,是位于PPDU结构中的,因此,针对非基于触发帧的物理层协议数据单元,接收端,如站点,可以将信令字段与数据分组作为整体进行接收。Correspondingly, these signaling fields are located in the PPDU structure as shown in Figure 10. Therefore, for the physical layer protocol data unit that is not based on the trigger frame, the receiving end, such as the station, can integrate the signaling field and the data packet as a whole To receive.
203、当传输方式指示信息所指示的传输方式为OFDMA传输时,站点从所述信令字段或触发帧中解析所述资源单元分配子字段,并根据所述资源单元分配子字段,接收或发送数据分组;203. When the transmission mode indicated by the transmission mode indication information is OFDMA transmission, the station parses the resource unit allocation subfield from the signaling field or trigger frame, and receives or transmits according to the resource unit allocation subfield. Data grouping
204、当传输方式指示信息所指示的传输方式为非OFDMA传输时,站点从所述信令字段或触发帧中解析前导码打孔指示信息,并根据所述前导码打孔指示信息,接收或发送数据分组。204. When the transmission mode indicated by the transmission mode indication information is non-OFDMA transmission, the station parses the preamble puncturing indication information from the signaling field or the trigger frame, and according to the preamble puncturing indication information, receives or Send data packets.
需要说明的是,步骤203和步骤204之间并没有先后顺序。另外,本申请实施例还提供几种可选的前导码打孔信息的指示方式,具体可参见下文所述。It should be noted that there is no sequence between step 203 and step 204. In addition, the embodiment of the present application also provides several optional indication methods of the preamble puncturing information. For details, please refer to the following description.
可见,本申请实施例针对非OFDMA传输,可根据前导码打孔指示信息进行数据分组的接收或发送;针对OFDMA传输,可根据资源单元分配子字段进行数据分组的接收或发送。从而能够降低指示分配的资源单元所需的开销。It can be seen that for non-OFDMA transmission, the embodiment of the present application can receive or send data packets according to the preamble puncturing indication information; for OFDMA transmission, data packets can be received or sent according to resource unit allocation subfields. Thereby, the overhead required to indicate the allocated resource unit can be reduced.

该实施方式中,该指示可指示160MHz内可能性最高或较高的被打孔情况的前导码打孔信息,从而有利于改善前导码打孔指示的灵活性同时,降低指示所需的比特开销。In this implementation manner, the indication can indicate the preamble puncturing information with the highest or higher probability of being punctured within 160 MHz, thereby helping to improve the flexibility of the preamble puncturing indication and reducing the bit overhead required for the indication. .
又一种可选的实施方式中,160MHz包括频率最高的80MHz和频率最低的80MHz,所述指示用于指示160MHz内的以下一个或多个前导码打孔信息:In another optional implementation manner, 160 MHz includes 80 MHz with the highest frequency and 80 MHz with the lowest frequency, and the indication is used to indicate one or more of the following preamble puncturing information within 160 MHz:

该实施方式中,该指示可指示160MHz内部分可能的前导码打孔信息,如前导码打孔的大小和位置可与信道划分的资源单元对应,从而有利于基于前导码打孔指示信息确定被分配的资源单元,以及降低该指示的比特位数。In this implementation manner, the indication may indicate some possible preamble puncturing information within 160 MHz. For example, the size and position of the preamble puncturing may correspond to the resource unit divided by the channel, thereby facilitating the determination of the preamble puncturing information based on the preamble puncturing indication information. The allocated resource unit, and the number of bits to reduce the indication.
请参阅图14,图14为本申请提供的另一种信道分布的示意图。如图14所示,图14将图7所示的160MHz的信道分布,划分为各可选的前导码打孔的大小和位置所对应的索引。也就是说,图14中,一个索引对应的一个或多个信道,为160MHz中的一种前导码打孔的大小和位置。Please refer to FIG. 14, which is a schematic diagram of another channel distribution provided by this application. As shown in FIG. 14, FIG. 14 divides the 160 MHz channel distribution shown in FIG. 7 into indexes corresponding to the size and position of each optional preamble puncturing. That is to say, in FIG. 14, one or more channels corresponding to an index are the size and position of a preamble puncturing in 160 MHz.
因此,上述160MHz内其中一个20MHz的前导码打孔信息,即为图14中索引0至7中的其中一个对应的前导码打孔信息;频率最低的80MHz内频率最低的两个20MHz构成的40MHz的前导码打孔信息,为图14中索引8对应的前导码打孔信息;频率最低的80MHz内频率最高的两个20MHz构成的40MHz的前导码打孔信息,为图14中索引9对应的前导码打孔信息;频率最高的80MHz内频率最低的两个20MHz构成的40MHz的前导码打孔信息,为为图14中索引10对应的前导码打孔信息;频率最高的80MHz内频率最高的两个20MHz构成的40MHz的前导码打孔信息,为图14中索引11对应的前导码打孔信息;频率最低的80MHz的前导码打孔信息,为图14中索引12对应的前导码打孔信息;频率最高的80MHz的前导码打孔信息,为图14中索引13对应的前导码打孔信息。Therefore, one of the 20MHz preamble puncturing information in the above 160MHz is the preamble puncturing information corresponding to one of the indexes 0 to 7 in Figure 14; the 40MHz constituted by the two lowest frequency 20MHz within the lowest frequency 80MHz The preamble puncturing information is the preamble puncturing information corresponding to index 8 in Figure 14; the 40MHz preamble puncturing information composed of two 20MHz with the highest frequency within 80MHz with the lowest frequency is corresponding to index 9 in Figure 14. Preamble puncturing information; the 40MHz preamble puncturing information composed of two 20MHz with the lowest frequency within the highest frequency 80MHz is the preamble puncturing information corresponding to index 10 in Figure 14; the highest frequency within 80MHz is the highest frequency The 40MHz preamble puncturing information composed of two 20MHz is the preamble puncturing information corresponding to index 11 in Figure 14; the 80MHz preamble puncturing information with the lowest frequency is the preamble puncturing corresponding to index 12 in Figure 14 Information: The 80MHz preamble puncturing information with the highest frequency is the preamble puncturing information corresponding to index 13 in Figure 14.
相应地,如表3所示,第一列的各索引分别对应各前导码打孔信息。该指示需要能够指示160MHz内的15种前导码打孔信息中的任一种,故该指示可占用4个比特位。Correspondingly, as shown in Table 3, each index in the first column corresponds to each preamble puncturing information. The indication needs to be able to indicate any of the 15 types of preamble puncturing information within 160 MHz, so the indication can occupy 4 bits.
表3中,如图14所示,索引0至7对应的前导码打孔信息为前导码打孔的大小为20MHz的前导码打孔信息。例如,该指示为0000,可表示前导码打孔的位置和大小为索引0对应的前导码打孔信息;该指示为0001,可表示前导码打孔的位置和大小为索引1对应的前导码打孔信息;等等。表3中索引8-11,可分别表示前导码打孔的大小为40MHz的前导码打孔信息。表3中索引12至13,可分别表示前导码打孔的大小为80MHz的前导码打孔信息。表3中索引14,可分别表示前导码无打孔,索引15为预留。索引个数表示每种描述的前导码打孔情况所对应的总个数。例如,第一行中索引个数8,表示索引0至7共对应8个前导码打孔的大小为20MHz的前导码打孔信息。相应地,表3中第一行至第三行可将索引 个数的索引展开,每行对应一个索引。In Table 3, as shown in FIG. 14, the preamble puncturing information corresponding to indexes 0 to 7 is the preamble puncturing information with a size of the preamble puncturing of 20 MHz. For example, the indication is 0000, which can indicate that the position and size of the preamble puncture is the preamble puncturing information corresponding to index 0; the indication is 0001, which can indicate that the position and size of the preamble puncture is the preamble corresponding to index 1. Punch information; etc. Indices 8-11 in Table 3 can respectively indicate preamble puncturing information with a size of 40 MHz preamble puncturing. Indices 12 to 13 in Table 3 can respectively indicate preamble puncturing information with a preamble puncturing size of 80 MHz. Index 14 in Table 3 can respectively indicate that the preamble is not punctured, and index 15 is reserved. The number of indexes indicates the total number of preamble puncturing situations described in each description. For example, the number of indexes in the first row is 8, which means that indexes 0 to 7 correspond to 8 preamble puncturing information with a size of 20 MHz. Correspondingly, the first to third rows in Table 3 can expand the number of indexes, and each row corresponds to an index.
可见,这种指示方式中,索引可指示前导码打孔的位置和大小。与直接指示前导码打孔后的离散的多资源单元的方式相比,采用前导码打孔指示信息能够降低信令开销。It can be seen that in this indication mode, the index can indicate the position and size of the preamble puncture. Compared with the method of directly indicating the discrete multi-resource unit after the preamble puncturing, the use of the preamble puncturing indication information can reduce the signaling overhead.
在一种可选的实施方式中,所述160MHz包括频率最高的80MHz和频率最低的80MHz,所述指示还用于指示160MHz内的以下一个或多个前导码打孔信息:所述频率最高的80MHz内的中间频率的40MHz,或者所述频率最低的80MHz内的中间频率的40MHz。In an optional implementation manner, the 160 MHz includes the highest frequency 80 MHz and the lowest frequency 80 MHz, and the indication is also used to indicate one or more of the following preamble puncturing information within 160 MHz: the highest frequency 40 MHz of the intermediate frequency within 80 MHz, or 40 MHz of the intermediate frequency within 80 MHz of the lowest frequency.

相应地,基于图8所述的资源单元分布示意图,可获得160MHz内资源单元与信道之间的对应关系,例如,图15所示,160MHz内各20MHz与242-tone RU之间的对应关系,从左到右,频率从低到高。表3中的各索引对应的前导码打孔的大小和位置如图15所示。以下结合图14或图15,以及表3所示的各索引为例,阐述前导码打孔指示信息所对应的前导码打孔信息。Correspondingly, based on the resource unit distribution schematic diagram described in FIG. 8, the corresponding relationship between resource units and channels in 160 MHz can be obtained. For example, as shown in FIG. 15, the corresponding relationship between each 20 MHz and 242-tone RU in 160 MHz can be obtained. From left to right, the frequency is from low to high. The size and position of the preamble puncturing corresponding to each index in Table 3 are shown in FIG. 15. The following describes the preamble puncturing information corresponding to the preamble puncturing indication information with reference to FIG. 14 or FIG. 15 and the indexes shown in Table 3 as examples.
数据分组的带宽为160MHz,前导码打孔指示信息可包括第一指示,该第一指示用于指示160MHz内的一个前导码打孔信息。The bandwidth of the data packet is 160 MHz, and the preamble puncturing indication information may include a first indication, and the first indication is used to indicate a preamble puncturing information within 160 MHz.
例如,如图16所示,该160MHz包括8个20MHz或8个242-tone RU,假设第一指示为0001,则站点可根据表3,确定数据分组的前导码打孔的大小和位置为如图16中网格填充的20MHz;相应地,站点可在除网格填充的20MHz之外的其余7个20MHz上或其余7 个20MHz对应的7个242-tone RU上接收或发送数据分组。For example, as shown in Figure 16, the 160MHz includes 8 20MHz or 8 242-tone RUs. Assuming that the first indication is 0001, the station can determine the size and position of the preamble puncturing of the data packet according to Table 3 as follows: The grid-filled 20MHz in Figure 16; correspondingly, the station can receive or send data packets on the remaining 7 20MHz excluding the grid-filled 20MHz or 7 242-tone RUs corresponding to the remaining 7 20MHz.
再例如,如图17所示,该160MHz包括4个40MHz,假设第一指示为0101,则站点可根据表3,确定数据分组的前导码打孔的大小和位置为如图17中网格填充的40MHz;相应地,站点可在除该网格填充的40MHz之外的其余3个40MHz上或其余3个40MHz对应的3个484-tone RU上接收或发送数据分组。For another example, as shown in Figure 17, the 160MHz includes four 40MHz. Assuming that the first indication is 0101, the station can determine the size and position of the preamble puncturing of the data packet according to Table 3 as shown in the grid filling in Figure 17. Correspondingly, the site can receive or send data packets on three 484-tone RUs corresponding to the remaining three 40MHz or the remaining three 40MHz excluding the 40MHz filled by the grid.
数据分组的带宽为320MHz,前导码打孔指示信息包括第一指示和第二指示,第一指示用于指示该320MHz内频率最低的160MHz内的前导码打孔信息;第二指示用于指示该320MHz内频率最高的160MHz内的前导码打孔信息。可见,针对320MHz带宽上的多个资源单元,基于表3采用8个比特位的前导码打孔指示信息进行指示即可。The bandwidth of the data packet is 320MHz, and the preamble puncturing indication information includes a first indication and a second indication. The first indication is used to indicate the preamble puncturing information in the 160MHz with the lowest frequency in the 320MHz; the second indication is used to indicate the The preamble puncturing information in the 160MHz with the highest frequency in 320MHz. It can be seen that for multiple resource units on the 320 MHz bandwidth, it is sufficient to use 8-bit preamble puncturing indication information based on Table 3 to indicate.
例如,如图18所示,320MHz包括16个20MHz或16个242-tone RU,假设前导码打孔指示信息中第一指示为0111,第二指示为0000,那么,站点可确定前导码打孔的大小和位置为:如图18所示,频率最低的160MHz内网格填充的20MHz和频率最高的160MHz内网格填充的20MHz;进而,站点可在320MHz内其余的信道或资源单元上,如图9中除网格填充的20MHz之外的14个20MHz或该14个20MHz对应的14个242-tone RU上,发送或接收数据分组,该情况下等效带宽为280MHz。For example, as shown in Figure 18, 320MHz includes 16 20MHz or 16 242-tone RUs. Assuming that the first indication in the preamble puncturing indication information is 0111 and the second indication is 0000, then the station can determine the preamble puncturing The size and location of is: as shown in Figure 18, 20MHz filled with grids within 160MHz with the lowest frequency and 20MHz filled with grids within 160MHz with the highest frequency; further, the site can be on the remaining channels or resource units within 320MHz, such as In FIG. 9, except for the grid-filled 20MHz, 14 20MHz or 14 242-tone RUs corresponding to the 14 20MHz send or receive data packets. In this case, the equivalent bandwidth is 280MHz.
再例如,如图19所示,320MHz包括16个20MHz,或16个242-tone RU,或8个242-tone RU和4个484-tone RU,假设前导码打孔指示信息中第一指示为0111,第二指示为1000,那么,站点可确定前导码打孔的大小和位置为:如图19所示,频率最低的160MHz内的网格填充的20MHz,以及频率最高的160MHz内的网格填充的40MHz;进而,站点可在320MHz内除网格填充的20MHz、40MHz之外的各20MHz或对应的各242-tone RU、484-tone RU上,发送或接收数据分组,即等效带宽为260MHz。For another example, as shown in Figure 19, 320MHz includes 16 20MHz, or 16 242-tone RU, or 8 242-tone RU and 4 484-tone RU, assuming that the first indication in the preamble puncturing indication information is 0111, the second indication is 1000, then the site can determine the size and position of the preamble puncturing: as shown in Figure 19, the grid fills 20MHz within 160MHz with the lowest frequency, and the grid within 160MHz with the highest frequency Filled 40MHz; Furthermore, the site can send or receive data packets at each 20MHz or the corresponding 242-tone RU, 484-tone RU except for the grid-filled 20MHz and 40MHz within 320MHz, that is, the equivalent bandwidth is 260MHz.
又例如,如图20所示,320MHz包括16个20MHz,或16个242-tone RU,或8个484-tone RU,假设前导码打孔指示信息中第一指示为1000,第二指示为0000,那么,站点可确定前导码打孔的大小和位置为:如图20所示,频率最低的160MHz内的网格填充的40MHz,以及频率最高的160MHz内的线条网格填充的20MHz;进而,站点可在320MHz内除网格填充的20MHz、40MHz之外的各20MHz或对应的各242-tone RU、484-tone RU上,发送或接收数据分组。For another example, as shown in Figure 20, 320MHz includes 16 20MHz, or 16 242-tone RU, or 8 484-tone RU, assuming that the first indicator in the preamble puncturing indicator information is 1000, and the second indicator is 0000 , Then, the site can determine the size and position of the preamble puncturing as: as shown in Figure 20, the grid-filled 40MHz within 160MHz with the lowest frequency and 20MHz with the line grid-filled within 160MHz with the highest frequency; further, The station can send or receive data packets on each 20MHz or corresponding 242-tone RU and 484-tone RU except for 20MHz and 40MHz filled with grids within 320MHz.
又例如,如图21所示,320MHz包括16个20MHz,或16个242-tone RU,或8个484-tone RU,假设前导码打孔指示信息中第一指示为1011,第二指示也为1000,那么,站点可确定前导码打孔的大小和位置为:如图21所示,频率最低的160MHz内的网格填充的40MHz,以及频率最高的160MHz内的网格填充的40MHz;进而,站点可在320MHz内其余前导码无打孔的信道或资源单元上,即等效带宽240MHz上,发送或接收数据分组。For another example, as shown in Figure 21, 320MHz includes 16 20MHz, or 16 242-tone RU, or 8 484-tone RU, assuming that the first indicator in the preamble puncturing indicator information is 1011, and the second indicator is also 1000, then the site can determine the size and position of the preamble puncturing: as shown in Figure 21, the grid-filled 40MHz within the lowest frequency 160MHz, and the grid-filled 40MHz within the highest frequency 160MHz; further, The station can send or receive data packets on channels or resource units without puncturing the remaining preambles within 320MHz, that is, on the equivalent bandwidth of 240MHz.
一种可选的实施方式中,同一指示在不同带宽大小下所对应的前导码打孔信息不同,从而有利于降低前导码打孔指示信息所需指示的前导码打孔信息的个数,进而降低前导码打孔指示信息所需的比特位数。In an optional implementation manner, the same indication corresponds to different preamble puncturing information under different bandwidth sizes, thereby helping to reduce the number of preamble puncturing information that needs to be indicated by the preamble puncturing indication information, and then Reduce the number of bits required for the preamble puncturing indication information.

For example, for a bandwidth of 320MHz, there are 13 situations for the position of any four adjacent 20MHz 80MHz holes. One index corresponds to one position. The second indication can indicate the index to inform the site that the 80MHz hole is within 320MHz. Location.
其中,针对表5所述的各条目,第一指示能够指示的条目索引的数量,即能够指示的孔的大小数量,与其比特数有关。比如,第一指示可占用较少的比特数,指示表5中的部分条目索引。相应地,针对每种大小的孔,第二指示所能够指示的前导码打孔的位置的条目索引数也与第二指示的比特数有关。第二指示可指示表6中的部分或全部条目索引。Among them, for each item described in Table 5, the number of item indexes that can be indicated by the first indication, that is, the number of hole sizes that can be indicated, is related to the number of bits. For example, the first indication may occupy a small number of bits, indicating the index of some entries in Table 5.

第三种,前导码打孔指示信息结合带宽指示信息,指示前导码打孔信息The third type, the preamble puncturing indication information is combined with the bandwidth indication information to indicate the preamble puncturing information
与上述各实施方式中采用前导码打孔指示信息指示带宽中的前导码打孔信息不同,本申请还提供又一种前导码打孔信息的指示方法。该指示方法中,由带宽指示信息和前导码打孔指示信息联合指示带宽中的前导码打孔信息。Different from using the preamble puncturing indication information in the foregoing embodiments to indicate the preamble puncturing information in the bandwidth, this application also provides another method for indicating the preamble puncturing information. In this indication method, the bandwidth indication information and the preamble puncturing indication information jointly indicate the preamble puncturing information in the bandwidth.
一种可选的实施方式中,带宽指示信息用于指示数据分组是否存在前导码打孔。若存在前导码打孔,带宽指示信息可指示主80MHz信道的前导码打孔情况;前导码打孔指示信息用于指示数据分组的其他前导码打孔情况,从而有利于支持更多的打孔数量,比如通过带宽字段指示某一个孔,前导码打孔指示信息再指示1~2个孔。若前导码无打孔或为非打孔模式,触发帧或数据分组中无需指示前导码打孔信息。In an optional implementation manner, the bandwidth indication information is used to indicate whether there is preamble puncturing in the data packet. If there is preamble puncturing, the bandwidth indication information can indicate the preamble puncturing of the main 80MHz channel; the preamble puncturing indication information is used to indicate the puncturing of other preambles of the data packet, which is helpful for supporting more puncturing. The quantity, for example, indicates a certain hole through the bandwidth field, and the preamble puncturing indication information indicates 1 to 2 holes. If the preamble is not punctured or is in a non-punctured mode, there is no need to indicate the preamble puncturing information in the trigger frame or data packet.
结合前文图12所述的实施例,触发帧或数据分组中是否存在前导码打孔指示信息,或是否利用资源单元分配子字段来指示前导码打孔信息,与数据分组的传输方式有关,或者与数据分组的传输方式以及带宽指示信息有关,或者与带宽指示信息有关。With reference to the embodiment described in Figure 12 above, whether there is preamble puncturing indication information in the trigger frame or data packet, or whether the resource unit allocation subfield is used to indicate the preamble puncturing information is related to the transmission mode of the data packet, or It is related to the transmission mode of the data packet and the bandwidth indication information, or is related to the bandwidth indication information.
其中,带宽指示信息可为触发帧或数据分组中的带宽字段。Wherein, the bandwidth indication information may be a bandwidth field in a trigger frame or a data packet.
例如,带宽指示信息用于指示的数据分组的前导码打孔情况如表8所示,各索引不仅与数据分组的带宽对应,还与主80MHz信道的前导码打孔情况相对应。其中,“80MHz非打孔模式(没有打孔)”表示该带宽中前导码无打孔;“80+80MHz”表示为两个80MHz构成 的非连续的160MHz带宽;“160+80MHz”表示为160MHz与80MHz构成的非连续的240MHz带宽。索引为6、8、10、12对应的数据分组的带宽以及主80MHz信道的前导码打孔情况,即为该数据分组的整体前导码打孔情况。其中,当带宽指示信息为6时,可不必结合前导码打孔指示信息进行数据分组的发送或接收。对于带宽指示信息为0、1、2、3、4、5时,明确指示数据分组的前导码无打孔,因此,也不必结合前导码打孔指示信息进行数据分组的发送或接收。对于带宽指示信息为7、8、9、10、11、12、13时,还需结合前导码打孔指示信息,进一步确定数据分组的前导码打孔信息。其中,带宽指示信息为8、10、12时,基于表8可明确P80的前导码打孔情况,对于其他信道的前导码打孔情况可结合前导码打孔指示信息确定。For example, the preamble puncturing situation of the data packet indicated by the bandwidth indication information is shown in Table 8. Each index not only corresponds to the bandwidth of the data packet, but also corresponds to the preamble puncturing situation of the main 80MHz channel. Among them, "80MHz non-punctured mode (without puncturing)" means that the preamble in the bandwidth is not punctured; "80+80MHz" means two 80MHz non-contiguous 160MHz bandwidths; "160+80MHz" means 160MHz Discontinuous 240MHz bandwidth formed with 80MHz. The index is the bandwidth of the data packet corresponding to 6, 8, 10, and 12 and the preamble puncturing situation of the main 80MHz channel, that is, the overall preamble puncturing situation of the data packet. Wherein, when the bandwidth indication information is 6, there is no need to combine the preamble puncturing indication information to send or receive data packets. When the bandwidth indication information is 0, 1, 2, 3, 4, 5, it is clearly indicated that the preamble of the data packet is not punctured. Therefore, it is not necessary to combine the preamble puncturing indication information to send or receive the data packet. When the bandwidth indication information is 7, 8, 9, 10, 11, 12, and 13, it is also necessary to combine the preamble puncturing indication information to further determine the preamble puncturing information of the data packet. Among them, when the bandwidth indication information is 8, 10, 12, the P80 preamble puncturing situation can be clarified based on Table 8, and the preamble puncturing situation of other channels can be determined in conjunction with the preamble puncturing indication information.
可见,该实施方式所述的前导码打孔信息的指示方法可降低前导码打孔指示信息的开销或能够指示何时基于该前导码打孔指示信息进行数据分组的接收或发送,何时不基于前导码打孔指示信息进行数据分组的接收或发送,从而有利于节省信令开销。It can be seen that the method for indicating preamble puncturing information described in this embodiment can reduce the overhead of preamble puncturing indication information or can indicate when to receive or send data packets based on the preamble puncturing indication information, and when not to The data packet is received or sent based on the preamble puncturing indication information, thereby helping to save signaling overhead.

针对表8所述的各条目,带宽指示信息可基于其比特数确定能够指示的条目索引的数量,比如,带宽指示信息可占用较少的比特数,指示表8中的部分条目。For each entry described in Table 8, the bandwidth indication information may determine the number of item indexes that can be indicated based on the number of bits. For example, the bandwidth indication information may occupy a small number of bits and indicate some entries in Table 8.
本申请实施例中,所述数据分组的传输方式是正交频分多址(OFDMA)传输,所述站点根据所述资源单元分配子字段,确定被分配的多个资源单元。由于OFDMA传输,前导码打孔之后的离散的资源单元需要分配给多个不同的站点,故需要采用触发帧中或信令字段中的资源单元分配子字段来指示可能的资源单元组合情况。如表9所示,索引号0至67所对应的资源单元为一个资源单元;索引号68至130所对应的资源单元为多个资源单元的合并或组合。可见,对于OFDMA传输,资源单元分配子字段可通过指示这些索引,告知每个站点被分配的资源单元。In the embodiment of the present application, the transmission mode of the data packet is Orthogonal Frequency Division Multiple Access (OFDMA) transmission, and the station determines the multiple resource units to be allocated according to the resource unit allocation subfield. Due to OFDMA transmission, the discrete resource units after preamble puncturing need to be allocated to multiple different sites, so the resource unit allocation subfield in the trigger frame or in the signaling field needs to be used to indicate possible resource unit combinations. As shown in Table 9, the resource unit corresponding to index numbers 0 to 67 is a resource unit; the resource unit corresponding to index numbers 68 to 130 is a combination or combination of multiple resource units. It can be seen that for OFDMA transmission, the resource unit allocation subfield can inform each site of the resource unit allocated by indicating these indexes.
表9中,索引72-79对应的,80MHz频带范围中某一个20MHz中,52-tone RU与该20MHz中同侧相邻的26-tone RU的合并方案中,“同侧相邻”与该20MHz在该80MHz频带范围中的位置有关。自左向右对应着80MHz频率由低到高,若该20MHz在该80MHz频带范围内中心位置的左侧,则该“同侧相邻”为“左侧相邻”,若该20MHz在该80MHz频带范围内中心位置的右侧,则该“同侧相邻”为“右侧相邻”。例如,结合图8所示的资源单元分布示意图,假设该20MHz为80MHz中频率最低的20MHz,因此,“同侧相邻”是指“左侧相邻”,52-tone RU为该20MHz中的第二个52-tone RU,那么,该20MHz中与该52-tone RU同侧相邻的26-tone RU为该20MHz中的第二个26-tone。故80MHz频带范围中频率最低的20MHz中,52-tone RU与该20MHz中同侧相邻的26-tone RU的合并方案为:该20MHz中第二个26-tone与第二个52-tone RU的合并。In Table 9, corresponding to the index 72-79, in a certain 20MHz in the 80MHz frequency band, the 52-tone RU and the 26-tone RU adjacent to the same side in the 20MHz band are merged. The position of 20MHz in the 80MHz frequency band is related. From left to right corresponds to the 80MHz frequency from low to high. If the 20MHz is on the left side of the center position in the 80MHz frequency band, then the "adjacent on the same side" is "adjacent to the left", if the 20MHz is at the 80MHz To the right of the center position within the frequency band, the "adjacent on the same side" is "adjacent to the right". For example, in conjunction with the resource unit distribution diagram shown in Figure 8, suppose that the 20MHz is the 20MHz with the lowest frequency in 80MHz. Therefore, "adjacent on the same side" means "adjacent to the left", and 52-tone RU is the 20MHz in the 20MHz The second 52-tone RU, then, the 26-tone RU adjacent to the 52-tone RU in the 20 MHz is the second 26-tone RU in the 20 MHz. Therefore, in the 20MHz with the lowest frequency in the 80MHz frequency band, the combination of 52-tone RU and the adjacent 26-tone RU on the same side in the 20MHz band is: the second 26-tone and the second 52-tone RU in the 20MHz The merger.
相应地,其余索引所指示的RU合并方案可结合图8进行确定,此处不再详述。Correspondingly, the RU merging scheme indicated by the remaining indexes can be determined in conjunction with FIG. 8, and will not be described in detail here.

其中,资源单元分配子字段占用7个比特位时,资源单元分配子字段可指示表9中的部分条目或RU合并情况。即针对表9所述的各条目,资源单元分配子字段可基于其比特数确定能够指示的条目索引的数量,比如,资源单元分配子字段可占用较少的比特数,指示表9中的部分条目。Wherein, when the resource unit allocation subfield occupies 7 bits, the resource unit allocation subfield may indicate some entries in Table 9 or the RU combination situation. That is, for each entry described in Table 9, the resource unit allocation subfield can determine the number of item indexes that can be indicated based on the number of bits. For example, the resource unit allocation subfield can occupy a smaller number of bits, indicating the part in Table 9. entry.
对于非OFDMA传输,也可以将各种前导码打孔信息配置在一个前导码打孔指示信息的索引表中。例如,表10所示。另外,针对表10所述的各条目,前导码打孔指示信息可基于其比特数确定能够指示的条目索引的数量,比如,前导码打孔指示信息可占用较少的比特数,指示表10中的部分条目。For non-OFDMA transmission, various preamble puncturing information can also be configured in an index table of preamble puncturing indication information. For example, as shown in Table 10. In addition, for each entry described in Table 10, the preamble puncturing indication information can determine the number of item indexes that can be indicated based on the number of bits. For example, the preamble puncturing indication information can occupy a smaller number of bits, indicating that Table 10 Part of the entry in.

Wherein, Table 11 includes the preamble puncturing information in which the preamble punctured in Table 10 is one hole. Optionally, Table 11 may also include the puncturing information of all the preambles in Table 10. The preamble puncturing indication information can reuse the resource unit allocation subfield, so that it is beneficial for the station to determine the transmission mode of the data packet and the preamble puncturing condition according to the index indicated by the preamble puncturing indication information.
